Exporting Results

Export flakiness scores to various file formats for integration with CI dashboards, issue trackers, or custom tooling.

Formats

JUnit XML

cargo ninety-nine export junit results.xml

Produces standard JUnit XML. Tests with P(flaky) >= 5% are marked as failures with details in the failure message. Compatible with CI systems that parse JUnit reports (GitHub Actions, GitLab, Jenkins, etc.).

HTML Report

cargo ninety-nine export html report.html

Generates a self-contained HTML page with a styled table showing all test scores. Categories are color-coded. Suitable for sharing with teams or archiving.

CSV

cargo ninety-nine export csv results.csv

Produces a CSV file with columns:

test_name,probability_flaky,pass_rate,total_runs,consecutive_failures,category,confidence

Values containing commas, quotes, or newlines are properly escaped per RFC 4180.

JSON

cargo ninety-nine export json results.json

Produces a JSON array of flakiness score objects with full detail, including Bayesian parameters. Useful for programmatic consumption, custom dashboards, or piping into other tools.
